This invention relates to a new and kitchen utensil and more particularly and specifically to a dispensing device which has as its primary object the provision of a dispensing device which is afiixed to the container housing the fluent material to be dispensed eliminating the necessity of removing and replacing the container cap when using the contents thereof.

Another object of this invention is the provision of a dispenser of the character described which has a predetermined capacity such as a cup, teaspoon or tablespoon so that a measured amount of the contents of the container to which the dispenser is attached are made available to the user.

Still another object of this invention is the provision of a dispenser of the character described in which the capacity of the dispenser is changeable by the simple and easily accomplished operation of inter-changing parts.

Still another object of this invention is the provision of a dispenser of the character described which is easily operated and which is of a simple and inexpensive design.

Still further objects and advantages of this invention will readily appear to those skilled in the art when the following description is read in the light of the accompanying drawings in which:

Fig. l is a perspective side view of the container and dispenser.

Fig. 2 is a partial vertical section.

Fig. 3 is a longitudinal vertical section of the dispenser.

Fig. 4 is a top plan view of the dispenser.

Fig. 5 is a longitudinal elevation of the dispenser.

Fig. 6 is a vertical end view of the dispenser supporting means.

Referring now to the accompanying drawings in which like numerals indicate similar parts throughout the drawings, A designates a kitchen container for fluent materials such as flour, sugar or the like which is provided at its open upper end i with threads 2 adapting it to receive the threaded cover-like member 3 of the dispenser B.

The dispenser B comprises the threaded coverlike member 3 which may be a conventional screw-top, adapted to cover the open end of container A.

There is a cut-out aperture in the center of the flat end wall of this cap 3, which aperture is substantially rectangular in shape.

A pair of vertical standards 5 and 6 are secured to the end wall of cap 3, one at each end of aperture 4 and substantially centered on the longitudinal center line of the aperture. Each Standimproved .1 Claim. (01122-337) J ard comprises a U-shaped elongated member, the bight portion of which is secured, by suitable means such as welding or soldering, as at .l, to the end wall of the cap. v

A circular, hollow bearing member 8 is slidabl disposed between the two opposed legs of each standard, these legs having a channel-shaped cross-section to retain the bearing member therein. The two bearing members B-receive and journal a shaft 9 for rotation therein. 'Shaft 9 terminates at one end in a crank ill enabling the operator to-rotatethe shaft in the-bearing members 8, which bearing members are slidably supported in the standards 5 and 6.

A hollow cylindrical member I4 is secured on shaft 9 between the standards 5 and 6 and is rotatable with the shaft. This cylindrical member or cylinder I4 is of such a size and shape, and is so positioned relative to the dispenser cap or cover 3 that it fits into and closes the cap apertureA.

An elongated, generally rectangular opening 15 is provided in the shell of the cylinder M in a position such that it is disposed at the inner side of cover 3 when the cylinder is in one rotational position, to receive contents of container A, and is disposed outside of the cover when the cylinder is in another rotational position so that the contents therein may be dispensed in measured quantity into a suitable receptacle.

Raised stops l6 are affixed to the shell of the cylinder and provide limit stops for the two rotational positions thereof.

A respective tension spring I l is disposed in each bracket and connected at its corresponding end to the bight portion of the respective bracket and at its opposite end to the respective bearing member 8. These springs exert a downward or inward pull on the bearing members which is transmitted through shaft 2 to cylinder l4 and resiliently urges the cylinder into sealing engagement with the end wall of the cap along the edges of the cap aperture 4. Aperture 4 has a width less than the diameter of the cylinder so that the cylinder seats in sealing relationship therein.

In operation of the dispenser, the operator rotates the cylinder It by means of handle 10, against the frictional resistance between the cylinder and the cover occasioned by the pull of springs H to a position where the opening I5 is disposed within the dispenser cap 3, as shown in Figure 2, so that contents of the container may enter the cylinder l4 when the container is inverted. I

The cylinder is then rotated to its alternative 3 rotational position bringing the opening 15 to a position outside the cap or cover so that the contents in the cylinder may be discharged into a suitable receptacle, the cylinder shell when in this rotational position closing ofi the opening 4.

The s'izeof the cylinder may be made to accommodate any kitchen measure of contents, such as a cup or teaspoonful.

Various sized cylinders may be used by replacement. This replacement is accomplished by the removal of the cotter pin I! from behind the washer [8 on shaft 9 and withdrawing shaft 9 from the bearings and cylinderto allow another measuring cylinder to be placed on shaft 9, after whichthe shaft is resecured in operative association with the bearing members.

Having thus explained and described the invention, I claim:

The combination with an open-ended container; of a dispenser for fluent materials oper- Lativ'ely associated with the open end of the container, said dispenser comprising a screw-top having an elongated, rectangular aperture in the end wall thereof, a pair of U-shaped stand- .ards disposed one at each end of said aperture and having their bight portions secured to said top, a respective circular, hollow bearing member slidably mounted in each standard between the opposed legs thereof, a shaft journaled in said a said standards rotatable with said shaft, said cylinder having a diameter larger than the width of said aperture and a generally rectangular opening therein, limit stop means on said cylinder providing two rotational positions therefor in one 0f which said cylinder opening is disposed entirely at the inner side of said top and in the other of --which said opening is outside said stop, and a.

respective tension spring in each standard secured at one end to the bight portion of the stand ard and at its other end to the respective bearing member to resiliently urge said cylinder into sealing contact with said cover along the edges of said cover aperture.
